Nix: Stream error in the HTTP/2 framing layer

[edolstra]

Observed a few times from BinaryCacheStore:

unable to download ‘https://cache.nixos.org/nar/1vwg4rs3rqzy2pia1ll8cnz066m8pjhz3q8qnqj5mrz6ayxd5m9n.nar.xz’: Stream error in the HTTP/2 framing layer (92)
unable to download ‘https://cache.nixos.org/nar/023m6mfkb4akkb7zpmcg8z2r4ly5yvz9gfp7g8an5rwn4y96284q.nar.xz’: Stream error in the HTTP/2 framing layer (92)

This seems to be pretty random. It may be a bug in curl or in nghttp2, or a CloudFront issue.

Have others experienced this problem? Can we consider it fixed in view of the referenced commit?

I also experienced this/similar issue eg:
unable to download 'https://cache.nixos.org/nar/1n9cyv2q974r14yr6823zwkvfs4k80vlfpp3xh2jlgcqw2z2g5dn.nar.xz': HTTP error 200 (curl error: Stream error in the HTTP/2 framing layer);

To me it seems to be curl related (on slow connections especially?)

I am seeing this same error in conjunction with "error 9 while decompressing xz file" ... using a very slow internet connection. NixOS 18.09

[alexherbo2]

Same.

Meanwhile the error also surfaced here, but on a very fast connection (100 Mbit/s).

When executing nixos-rebuild switch,always with the error.

The "HTTP 200" errors were more lengthily discussed on the forum; maybe they are unrelated to these older errors from CloudFront cache.

I noticed that this happens if I run the CPU of my RaspberryPi 3B very slowly (<100MHz).

Does this have anything to do with CloudFront?

[vcunat]

cache.nixos.org isn't using CloudFront anymore – it's Fastly now: https://discourse.nixos.org/t/the-nixos-cache-is-now-hosted-by-fastly/1061

[ebzzry]

@vcunat OK. Does that mean that the diagnostic script linked at http://cache.nixos.org/ is no longer applicable?

Closing, probably not a Nix bug.
